What Is Dev Xvda

Virtual storage devices, representing cloud storage (or paravirtualized storage generally, as izx has pointed out), are typically exposed in Ubuntu through /dev/xvd nodes. /dev/xvda1 is the first partition of the first such device (just as /dev/sda1 is the first partition of the first SCSI or SCSI-like storage device).

What is SDA and XVDA?

The /dev/sda device is provided for support of legacy devices and installations that don’t understand Xen native virtual disks. The /dev/xvda1 device is the native device and the one you should use.

How do I free up space on dev xvda1?

1. Locating large files: sudo find / -type f -size +10M -exec ls -lh {} \;
2. Deleting large files: /bin/rm -f <path-to-large-file>
